My brother Lee shared one of my dad's favorite stories at his funeral. The Lamp Lighter. I don't remember all the specifics but it goes something like this.
"There is an old city. In this city there is a lamp lighter. He goes from street to street lighting the lamps for those in the town. No one sees him, or talks with him but you know he has passed through because of the light he has left and shared."
My dad was the ultimate sharer of light. I watch this video from time to time to see that light-His smile while he's playing the banjo, singing with his girl. He made me sing that song with him every time we went up to hear his band.
